I am not usually to bothered by digital noise at normal viewing size. But when does noise detract from the image itself? I would value opinions and would be extremely interested if you could post images that you have produced where noise is evident but you still consider the interest of the image dominant enough to override the technical imperfection. It would be also interested in any images where you believe noise adds to the artistic merit of the image.
The shot below clearly suffers from underexposure even though the metering was spotted off of the darker area of the image. It was taken ISO 800, 1/20th sec exposure. No tripod with camera rested on a bench. The noise is made worse by trying to recover exposure in UFRaw. Does this make it a 'bad' image? I am exploring what noise may have as an artistic merit rather than than a camera club indiscretion.
